496 CLASS INSI.CTA. 



piece is also bifid or armed with two horns in the males, whose 

 body is proportionally more narrow and more elongated, with 

 the abdomen growing remarkably narrow from front to rear, 

 even almost triangular; and the knob of the antennae is very 

 much elongated, compose the genus Macronota of M. Wied- 

 mann. But all these sections can only be well established 

 when a particular study shall be made of the numerous species 

 of the genus Cetonia of Fabricius. 



Those of Europe are provided with a scutellum of the 

 usual size. Such are 



Cetonia aurata^ Scarahceus auratus, Lin. Oliv. Col. I. b. 

 1. 1. nine lines in length, of a brilliant golden green above, 

 of a coppery red underneath, with white spots on the elytra. 

 Common on flowers, and often on those of the rose and elder- 

 trees. 



C. fastuosa, Fab. Panz. Faun. Insect. Germ. XLI. 16. 

 larger than the preceding, of an uniform golden green, with- 

 out spots, and with the tarsi blueish. South of France. 



S. sticficus, Lin. Panz. ibid. I. 4. five lines in length, 

 black, a little hairy, with white points ; those of the belly 

 arranged in two or three lines, according to sex. Very com- 

 mon on thistles.* 



The second tribe of Lamellicornes, the Lucanid.e, thus 

 named from the genus Lucanus of Linnaeus, have the knob 

 of the antennae composed of leaves or of teeth disposed per- 

 pendicularly to the axis, in the manner of a comb. These 

 organs have always ten articulations, the first of which is 

 usually by far the longest. The mandibles are always cor- 

 neous, most frequently projecting and larger, and even very 

 different in the males. The jaws of the majority terminate in

 volume of the Linnaean Trans,, with respect to the genera genuchus, 

 schizorhina and gnathocera, established at the expense of that of cetoniae.
